Be it known that We, WILLIAM H. BAKER, residing at Central Falls,Providence county, Rhode Island, and FREDERIC E. KIP, residing atMontclair, Essex county, New Jersey, citizens of the United States, haveinvented certain new and useful Improvements in Looms, of whichthefollowing is a specification.

This invention relates to double-shuttle looms, and has for its objectto provide means for supplying weft to the shuttles or weftcarriers ofthe loom as required through mech-' anism automatically controlled byexhaus tion-indicating devices made inoperative and,

operative, respectively, by. the presence or absence of weft or fillingin the active shutties.

In the accompanying drawings, which illustrate an embodiment of theinvention, Figure 1 is a side'elevation, on a relatively-small scale, ofa loom provided with our improvements; and Fig. 2 is a front elevationof the lay, showing the shuttle-boxes and picking mechanism.. Fig. 3 isa sectional side view on a larger scale, showing the construction morein detail; and Fig. 4 is a sectional front view on the same scale asFig. 3,'showing the magazine in vertical axialsection. Fig. 5 is 0 aview of the detent device detached. Fig.

6 is a detail View of the shuttle-box and shuttle therein as seen fromthe front. This view shows the electrical connections. Fig. 7 is asectional View of the shuttle and of the bobbin orweft-holder therein.Fig. 8 is'anenlarged View of the detachable spindle for the weft-holder.I

a is the loom-frame, and b the breast-beam,

tively mounteda drum-like magazine M to carry the weft tobe supplied tothe shuttles h in the boxes on the lay. This magazine consists of a heador end i, a sleeve-like boss j, and bars in, extending from said headparallel with the axis or boss, where theyare end of the magazine open.The bobbins m are held iu'place by suitable spring-clips 'n, so that thebobbins may be easily displaced laterally by drivers 0 and 0', whichdrive them into the shuttles in the respective boxes c and c, displacingtherefrom the empty bobbins. The magazine is rotated through a belt 12,which is driven from a sheave g on a shaft 1' of the loom and takes overa sheave s, ro- 6o tati vely mountedon the bossj of the magazine. Thissheave contains a spring i, one end of which is secured to the pulleyand the other to the boss The magazine is held against rotation by adetent device, to. be

hereinafter described, and when the springt is wound up the belt 19slips on the sheave 5. Therefore when the magazine is released it willbe instantly rotated by the spring 6..

' The. detentdevice' is best seen in Figs. 3 and 5. Itcomprises two likerocking detents u and 10, carried on an arm '2), which projects fromthebracket 9. Each detent rocks on a stud w, projecting out laterallyfrom the arm '0 and they arecoupled together by a link x, the linktakingfhold of the upper detent a back of the pivot and of the lowerdetent u in frontof the pivot,'so that when one detent rocks it rocksthe other'detent in the opposite direetion. To prevent thedetents fromrocking too far in,either direction, a stud y, extending'from thebracket-arm, engages a limiting-slot in the link as. The detents u and utake over the respective upper and lower bobbins m, presented at thedeliverypoint in front of the drivers 0 0 and prevent the rotation ofthe magazine (in the direction of the arrow 2 in Fig. 3) so long as bothbobbins are in place. If the upper bobbin be driven into the shuttle,the magazine will turn until '90 the lower bobbin takes theplace leftvacant, the next bobbin below rising to take thelower position; but ifthe lower bobbin be displaced the magazine will rotate until the bobbinnext below it takes the upper position-that 5 is, when the lower bobbinis displaced the magazine rotates to the extent of two bobbins.

The drivers 0 0 are fulcrumed at 1 on the loom-frame and havelaterally-projecting 1oo heads which extend into the open inner end ofthe magazine, and each driver carries pivoted to it below said fulcruman arm 2, which may by lowering it be put into the path of a tappet 3,carried by the lay. As herein shown, this tappet is fixed to one of thelayswords and is broad enough to actuate either of the arms 2, which maybe putinto its path. The respective arms 2are supported onarmature-levers 4 and 4, carrying the armatures 5 and 5 of twoelectromagnets 6 and 6, and when either magnet attracts its armature thecorresponding arm 2 is lowered into the path of the tappet 3, wherebywhen the lay beats up the driver to which said arm is attached drivesthe bobbin m in front of it at the delivery-point out laterally from themagazine into the shuttle, expelling at the same time the exhaustedbobbin from the shuttle in thebox. The magnets 6 and 6 are in electriccircuits 7, one of which is seen in Fig. 6, and the operation of therespective drivers is controlled by the presence or absence of weft inthe respective shuttles in play. Referring to Figs. 6 and 7, theelectrical construction will be described, premising that as eachshuttle and shuttle-box is fitted up electrically in the same way adescription of one box and shuttle will serve for both.

The shuttle'h has clips or spring-jaws 8 to keep the weft holder-orsupporter m in place.

This is a known device; but in this instance the clips are arrangedabove and below and not at the sides of the device which holds the weft.This device comprises a laterally-compressible metal spindle 9,detachable from the shuttle, and best seen in Fig. 8. This spindle isprovided with a headpiece 10,Which may be of wood, and about the latterare two metal bands or rings 11, which are embraced by the jaws 8. Theselatter hold the spindle firmly but detachably in the shuttle. The buttor end of the metal spindle is in electrical contact with a metal plate12 on the shuttle, and the plate 12 is electrically connected byasuitable conductor 18 with a metal contact-plate 13 on the face of theshuttle at that end, while the jaws 8 are connected electrically by asuitable conductor 19 with a metal contact-plate 13 at the other end ofthe shuttle. Thus the head of the spindle 9 is in electrical connectionwith the plate 13 and the rings 11- are in similar connection with theplate 13. Fixed in electrical contact with the end of the spindle is acontact-spring 14, which forms the indicator and plays in a slot in theblock 10 and tends normally to spring outward into electrical contactwith one or both of the rings 11, thus closing the circuit between theplates 13 and 13. The actual holder of theweft is a butt-cop 15, whichmav' be slipped on the spindle 9. This butt-cop (or it may be a fullbobbin) has a groove into which the free end of the spring 14 enterswhen the cop is slipped onto the spindle. Now if the cop or bobbincarries weft 16, as

erator to supply the circuit 20'. by employing suitably-arrangedconductors seen in Fig. 6, the spring-indicator 14 passes under the weftand is pressed inward, so as to break the contact between said indicatorand the ring or rings 11; but when the weft becomes substantiallyexhausted the springindicator will again close the circuit by formingcontact with the rings. Now when the shuttle enters its box the plates13 and 13 will be put into contact, respectively, with spring-terminals17 and 17 of the circuit, as seen in Fig. 6, thus completing the circuitthrough the electromagnet 6 or 6 belonging to this particularshuttle-box.

In Fig. 6, 2O designates any suitable gen- Of course one generator mayserve for energizing both magnets. This will be understood by anyelectrician.

The construction of the drivers 0 and 0, the magnets, and theoperating-tappet is substantially the same as those shown in our pendingapplication, Serial No. 9,493, filed March 21, 1900, and is notspecifically claimed herein.

The particular construction of the contact devices in the shuttle andbobbin is not material to our invention so long as it is controlled bythe presence or absence of weft therein. The contact-spring'17, held outof contact manually at the break by the overwrapped weft, may be asillustrated in our United States Patent No. 637,195, dated November 14.,1899.

The pickers 21 and the picker-stick 22 (seen in Figs. 1 and 2) possessno special or novel features, and indeed any kind of picker devicessuited to the purpose may be employed. The lay may be vibrated by meansof cranks in the shaft 4" and connecting-rods r in a known manner.

In Fig. 4 the weft-end holder 23 is indicated, but is represented forlack of room as partly broken away. There is nothing novel in thisfeature.

, The novel feature-of automatically supplying from a rotatable creel,feeder, drum, or magazine when required at the same time or on the samepick of the loom both the upper and lower shuttle or either the upper orthe lower shuttle of a double-shuttle loom, with a bobbin or weft-holdercontaining weft or filling to replace that substantially exhausted, thesaid mechanism being so constructed that when the upper shuttle has beensupplied the magazine will automatically rotate, so that it moves up tothe extent of only one bobbin or weft-holder and then stops, but whenthe lower shuttle has been supplied or when both the upper and lowershuttles happen to be supplied on the same pick of the loom the magazinewill automatically rotate, so that it moves up to the extent of twobobbins or weft-holders and then stops, is of course equally-welladapted to a mechanically-controlled weft-supply as anelectrically-controlled weft-supply-as, for example, themechanically-controlled weft-supply illustrated invour pendingapplication, Serial No. 15,786, filed May 7, 1900.

- By weft-holder, as herein expressed, is

- meant any receptacle holding weft or filling such as a weft or bobbincase containing weft or filling, or bobbin, butt-cop, cop, and the likecontaining weft or filling. 'lhe magazine herein illustrated is alsoadaptable to carry any known form of weft-holder.

By absence or substantial absence and exhaustion or substantialexhaustion of weft or filling from the shuttles in play, as hereinexpressed, is not necessarily meant the entire absence of the weft orfill-,

ing, but such degree of exhaustion as will allow theexhaustion-indicating device to perform its function. 1

The spindle 9 is split and laterally compressible, as in the common formof spindle used in shuttles.

Having thus described our invention, we claim 1. In a loom, thecombination with two superposed shuttle-boxes, and shuttles, bothadapted to receive and discharge weft-holders laterally, and means forpicking the shut tles from said boxes simultaneously, of a magazinecomprising a rotatable carrier provided with means for supportingweft-holders concentrically arranged about the axis of the carrier,means for moving said carrier, a detent for holding said carrier againstmovement normally with weft-holders opposite the superposed shuttleboxes, two drivers for driving the weft-holders from the carrierinto therespective boxes, means for actuating said drivers at proper times, andmeans controlled by the presence or absence of weft or filling in therespective shuttles for setting said drivers in operation. a
